Citrix NetScaler CPX is a container-based application delivery controller that can be provisioned on a Docker host.
NetScaler CPX allows you to:
NetScaler CPX Express is the free developer version that supports up to 20 Mbps and 250 SSL connections. CPX Express supports most of the CPX feature set, except TCP optimization and L7 DDoS.

NetScaler CPX is optimized for high TCP session count and high HTTP response-per-second performance.
Load balancing is at the heart of NetScaler CPX. Unlike Round Robin and hash-based load balancing, NetScaler CPX algorithms take into account the actual load and send traffic to the least-loaded containerized app. You can integrate Layer 7 policies required for deploying a service, and you can apply policies to both ingress and egress traffic. These policies can redirect a connection based on HTTP data, rewrite an HTTP request or response, and switch a connection to a specific app based on HTTP payload, HTTP heater, or IP address range. You can combine load balancing with DNS service groups or use NetScaler CPX as a DNS service.
NetScaler has built-in support for service discovery. NetScaler Management and Analytics System (MAS) ties into Mesos, Marathon, and Kubernetes, and acts as a CPX controller. It auto-configures NetScaler CPX to changes in the app topology. You can automate the configuration of NetScaler CPX to load-balance any type of app through Stylebooks—declarative templates that reside in NetScaler MAS.
NetScaler Management and Analytics System (MAS) acts a controller, orchestration point, and analytics platform for NetScaler CPX. You can manage multiple NetScaler CPXs at scale and get immediate visibility to the health of apps and microservices. NetScaler CPX streams its internal counters and transaction logs to NetScaler MAS. Several built-in insights provide detailed reporting on user experience, security, and SSL. You can manage NetScaler CPXs as a fleet through NetScaler MAS, with automated per-instance configuration and SSL certificates management. With NetScaler MAS as a controller, you can tie in to orchestration systems, SDN controllers, or overlay network solutions to insert NetScaler CPX into routed or host-network topologies.
NetScaler CPX has proven algorithms to manage attacks that exploit weaknesses in TCP, HTTP, and DNS. By using NetScaler CPX for all app-to-app traffic, you can protect apps from DDoS attacks from the outside and inside.
Deploy SSL/TLS with the most secure ciphers, such as elliptical curve cryptography. Mandate specific ciphers across all load balancers by using NetScaler Management and Analytics System SSL certificate management tools. NetScaler CPX can aggregate connections to backend servers to optimize performance and secure the connection to the backend apps by re-encrypting connections. You can push your apps to the cloud or separate production from pre-production traffic with confidence.
